What to do
• If the manager-subscription count is high, a background service is leaking connections — check the dialler worker (disable it if the client doesn't use automatic calling).
• Restart Asterisk during a quiet moment to clear the backlog: core restart when convenient
• Confirm the platform is on the latest version (the known leak is fixed in current releases).
• If it recurs after a restart, escalate to support with this alert.

This alert is sent once each time the event-bus load crosses a new threshold, and re-arms automatically when it recovers. It is an early warning — acting now prevents an outage.
